Why do you include Tomb Raider with those two? Unlike them It's not based on a movie?

Blade Runner is or isn't based on a movie depending on how you look at it. It is in the sense that it takes place in the same setting and includes several of the film's characters and locations. Then again it isn't in the sense that it doesn't tell the film's story at all, or even a story about the main character (like the Riddick games). It's a new character that experiences events occurring parallel to the film's timeline. Kinda super cool if you ask me. But I suppose it's more a case of it being based on the film than it not being based on the film :)

No it's a movie based on a game, then they made another game, it was kinda the opposite of what I asked. :P

It was Tomb Raider Legend - Lara Croft Tomb Raider ie, it's the wrong way around and it's the exact same IP.

Oh yes I see what you mean.
